SwiftyCrop - SwiftUI

Circle Mask Shape	Square Mask Shape	Liquid Glass UI

🔭 Overview

SwiftyCrop allows users to seamlessly crop images within their SwiftUI applications. It provides a user-friendly interface that makes cropping an image as simple as selecting the desired area.

With SwiftyCrop, you can easily adjust the cropping area, maintain aspect ratio, zoom in and out for precise cropping. You can also specify the cropping mask to be a square, circle or rectangle with custom aspect ratio. SwiftyCrop is highly customizable, you can adjust texts, fonts and colors that are used.

SwiftyCrop currently supports iOS, iPadOS, visionOS and macOS natively.

🧳 Requirements

• iOS 16.0 or later
• visionOS 1.0 or later
• macOS 13.0 or later
• Xcode 15.0 or later
• Swift 5.9 or later

💻 Installation

There are two ways to use SwiftyCrop in your project:

• using Swift Package Manager
• manual install (embed Xcode Project)

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

To integrate SwiftyCrop into your Xcode project using Xcode 15.0 or later, specify it in File > Swift Packages > Add Package Dependency...:

https://github.com/benedom/SwiftyCrop

Manually

If you prefer not to use any of dependency managers, you can integrate SwiftyCrop into your project manually. Put Sources/SwiftyCrop folder in your Xcode project. Make sure to enable Copy items if needed and Create groups.

📱 Demo App

To get a feeling how SwiftyCropView works you can run the demo app (thanks to @leoz).

🛠️ Usage

Quick Start

This example shows how to display SwiftyCropView in a full screen cover after an image has been set.

import SwiftUI
import SwiftyCrop

struct ExampleView: View {
    @State private var showImageCropper: Bool = false
    @State private var selectedImage: UIImage?

    var body: some View {
        VStack {
            /*
            Update `selectedImage` with the image you want to crop,
            e.g. after picking it from the library or downloading it.

            As soon as you have done this, toggle `showImageCropper`.
            
            Below is a sample implementation:
             */

             Button("Crop downloaded image") {
                Task {
                    selectedImage = await downloadExampleImage()
                    showImageCropper.toggle()
                }
             }

        }
        .fullScreenCover(isPresented: $showImageCropper) {
            if let selectedImage = selectedImage {
                SwiftyCropView(
                    imageToCrop: selectedImage,
                    maskShape: .square
                ) { croppedImage in
                    // Do something with the returned, cropped image
                }
            }
        }
    }

    // Example function for downloading an image
    private func downloadExampleImage() async -> UIImage? {
        let urlString = "https://picsum.photos/1000/1200"
        guard let url = URL(string: urlString),
              let (data, _) = try? await URLSession.shared.data(from: url),
              let image = UIImage(data: data)
        else { return nil }

        return image
    }
}

‼️ NOTE ‼️

If you want to display `SwiftyCrop` inside a sheet, use `NavigationView` instead of `NavigationStack` in case you want to wrap it.

SwiftyCrop supports three different mask shapes for cropping:

• circle
• square
• rectangle

This is only the shape of the mask the user will see when cropping the image. The resulting, cropped image will always be a square by default when using circle or square. To get a circular cropped image, you can override this using a configuration.

You can also configure SwiftyCropView by passing a SwiftyCropConfiguration. A configuration has the following properties:

Property	Description
maxMagnificationScale	CGFloat: The maximum scale factor that the image can be magnified while cropping. Defaults to 4.0.
maskRadius	CGFloat: The radius of the mask used for cropping. Defaults to 130. A good way is to make it dependend on the screens size.
cropImageCircular	Bool: When using the cropping mask circle, whether the resulting image should also be masked as circle. Defaults to false.
rotateImage	Bool: Whether the image can be rotated when cropping using pinch gestures. Defaults to false.
rotateImageWithButtons	Bool: Option to show rotation buttons for rotating. Defaults to false.
usesLiquidGlassDesign	Bool?: Apply the all new liquid glass design. Defaults to true if iOS 26 is available.
zoomSensitivity	CGFloat: Zoom sensitivity when cropping. Increase to make zoom faster / less sensitive. Defaults to 1.0.
rectAspectRatio	CGFloat: The aspect ratio to use when a rectangular mask shape is used. Defaults to 4:3.
texts	Texts: Defines custom texts for the buttons and instructions. Defaults to using localized strings from resources.
fonts	Fonts: Defines custom fonts for the buttons and instructions. Defaults to using system font.
colors	Colors: Defines custom colors for the texts and background. Defaults to white text and black background.

Create a configuration like this:

let configuration = SwiftyCropConfiguration(
    maxMagnificationScale: 4.0,
    maskRadius: 130,
    cropImageCircular: false,
    rotateImage: false,
    rotateImageWithButtons: false,
    usesLiquidGlassDesign: false,
    zoomSensitivity: 1.0,
    rectAspectRatio: 4/3,
    texts: SwiftyCropConfiguration.Texts(
        cancelButton: "Cancel",
        interactionInstructions: "Custom instruction text",
        saveButton: "Save"
    ),
    fonts: SwiftyCropConfiguration.Fonts(
        cancelButton: Font.system(size: 12),
        interactionInstructions: Font.system(size: 14),
        saveButton: Font.system(size: 12)
    ),
    colors: SwiftyCropConfiguration.Colors(
        cancelButton: Color.red,
        interactionInstructions: Color.white,
        saveButton: Color.blue,
        background: Color.gray
    )
)

and use it like this:

.fullScreenCover(isPresented: $showImageCropper) {
            if let selectedImage = selectedImage {
                SwiftyCropView(
                    imageToCrop: selectedImage,
                    maskShape: .square,
                    // Use the configuration
                    configuration: configuration
                ) { croppedImage in
                    // Do something with the returned, cropped image
                }
            }
        }

🪟 iOS 26 & Liquid Glass

To adopt to the new Liquid Glass design Apple introduced with iOS 26, SwiftyCrop supplies a new UI which reflects this design. This will remove text buttons and replace them with icon buttons and much more. Below is the current way it looks. By default, this is active if iOS 26 or macOS 26 is available. You can change this by overriding the SwiftyCropConfiguration.
